Keloids Are Not Dangerous

Rest assured that the chances of a keloid becoming cancerous is highly unlikely. However, if there are any other abnormal moles or skin growths on your body, it is best to schedule a full body skin check with a board certified dermatologist.

Confirm keloid diagnosis

Keloids are not an increased risk of cancer.  They result when the body "over responds" to injury.  However, it is also best to have any abnormal skin lesion evaluated by your skin care provider to confirm the diagnosis.

Treat keloids and undergo an examination to obtain the right diagnosis

Keloids are not at increasing risk of cancer.  However, I have seen patients who thought they had keloids, but in fact, had a skin lesion that was in fact more dangerous.

One can never say never, but carcinogenic transformation in a keloid would be highly unusual.  It would be described as a "case report", or medical oddball.  Dr. Oppenheim's comment about misdiagnosis is very true.

No Keloids Cannot Become Cancerous

  A keloid is due to an over-enthusiastic response to injury. It is benign overgrowth of fibrous tissue leaping over the boundaries of normal healing. 

  Occasionally, there can be a misdiagnosis. What is thought to be a keloid may in fact be a malignancy such as a dermatofibroma protuberans ( DFSP), a sclerotic basal cell carcinoma, or a malignancy developing from a scar, especially one that has been irradiated. However, a keloid itself, though sometimes growing, does not transform into a malignancy.

Any abnoramility in the skin can potentially become a skin cancer especially in the presence of chronic irritation. The question is what is the likelihood of that happening. In the case of keloids that likelihood is extremely low and would be more dependent on the cause of the keloid than the keloid itself.

With rare exception, do keloids become cancerous. Occaionally a skin cancer can be confused as as keloid. However, any scar has the potential to develop into a cancer. This is more likely with a longstanding burn and is called a Marjolin's ulcer.
